As authorities began investigating the mass shooting in Las Vegas Sunday night, Marilou Danley quickly became someone they wanted to talk to.
Investigators questioned her about Paddock's weapons purchases, a $100,000 wire transfer to a Philippine bank that appeared to be intended for her, and whether she saw any changes in his behaviour before she left the United States.
Lombardo said he found it hard to believe that the arsenal of weapons, ammunition and explosives recovered by police in their investigation could have been assembled by Paddock completely on his own.
Although the Federal Bureau of Investigation wants to talk to her, Marilou Danley, 62, is not in custody - she is classified as a "person of interest" to investigators - and is free to go wherever she wants, United States media reported.
In addition, investigators are examining a dozen financial reports filed in recent weeks when he bought more than US$10,000 in casino chips. If the suicide didn't destroy Paddock's brain, experts may even find a neurological disorder or malformation, he said.
Matthew Lombard, the attorney representing Danley, read a statement Wednesday from her, in which she said she knew Stephen Paddock as a "kind, caring man".
Investigators now believe Paddock meant to survive the massacre, Las Vegas police Sheriff Joseph Lombardo said.
Officers on the ground can be seen working their way towards Mandalay Bay Resort, where gunman Stephen Paddock was shooting. Sheriff Lombardo said some of the hospitals responsible for the counts realized they counted a few patients twice, or counted as concert shooting victims patients who came in with unrelated injuries.
"It never occurred to me in any way whatsoever that he was planning violence against anyone", she said in the statement.
However when asked if he felt any guilt about selling him the firearms, he said: "I don't, no".
The woman said Danley was "a good person" who would've stopped Paddock had she been in a position to do so. From the windows of his room, he shot at a crowd in a concert.
Meanwhile, the number of wounded in the Sunday night massacre has been lowered from more than 500 to 489. House Majority Leader Kevin McCarthy said he and Rep. Mark Amodei, a Nevada Republican, also will make the trip.
High up on the hotel's residential floors, a first responder radioed in: "I'm inside the Mandalay Bay on the 31st floor, I can hear automatic fire coming from one floor ahead. one floor above us".
Earlier, the president and first lady Melania Trump traveled to University Medical Center in Las Vegas.
His abrasive tweets and the comments he made Tuesday while visiting Puerto Rico, she said, made her think he may fail to show genuine compassion for Las Vegas. Paddock sent tens of thousands of dollars overseas before the shooting, ABC News reported Monday.
Nevada's Gaming Control Board said it will pass along records compiled on Paddock and his girlfriend to investigators.
